What does it " tk.Frame.__init__(self, *args, **kwargs) " mean?

Question

I am a newbie. I've seen tk.Frame.__init__(self, *args, **kwargs) this code here. I am really confused. What exactly this would do?

This is fundamental part of python's standard way of creating subclasses. It doesn't really have anything specific to do with tkinter. However, if you subclass a tkinter class -- like with any class -- this will make sure that the base class is properly initialized.

What you're seeing, however, is an older style of initializing a base class. For python 3.x and beyond you should be using something like super().__init__(*args, **kwargs). See super and the description of Class objects in the standard python documentation.
